This invention relates to a double container adapted particularly forthe shipment of ingredients for certain kinds of-paint,

such as aluminum and bronze paint, this are 6 ticle having twocompartments or container bodies, one for the liquid and the other forthe powder.

The object of the present invention is to provide a double container ofthis kind ineluding two container bodies, one adapted to be fittedinside the other and both adapted to be closed,a-Iid sealed in oneclosing operation and by the same closing member. I

A further object is to provide a construc- 5 tion wherein not only areboth containers closed in one closing operation but wherein each has agasket seal, the gasket scaling for both container bodies beingpreferably accomplished with the use of a single gasket.

In the accompanying sheet of drawings, Fig. 1 is a side elevation of myimproved double container with both container bodies in closed andsealed condition, parts being broken away; Fig. 2 is an enlargedfragmentary sectional view with the parts in the relative positionswhich they occupy prior'to the closing operation; Fig. 3 is a similarview after the closing operation; and Fig. 4 is a view similar to Fig. 3showing'a slight modification. I

My improved double container comprises two container bodies 10 and 11,the former being deeper and of slightly greater diameter than the latterso that the smaller container 11 can he slipped down into the open topof the larger container 10. In the use of this double container forshipment of paint ingredients, the liquid is placed in the-lar ercontainer and the aluminum, bronze or ot er powder in. the containerbody 11.

It will be observed that the larger or outer container 10 is provided atthe top with a roller bead 12 and that the inner container 11 has astraight body portion. of such diameter that it will just fit and slidedown inside of the head 12. Furthermore, the inner container body 11 isprovided at the top with an outwardly extending flange 13 which overliesthe head 12, and this container body has a cover'14 with a depressedpart'which fits tightly into the top of the container body 11, the coverhaving an outwardly extending flange 15 which overlies the flange 13 andpreferably extends outwardly somewhat furthe head 12, compressing thether than the flange 13. In fact, in the preferred embodiment, the outerperiphery of the flange 13 is near the circular center line of the head12 or it may project slightly beyond the same, while the flange 15projects outwardly beyond the flange 13 as above stated. o

0 In the preferred embodiment of the inven' tion, a single gasket 16 isemployed to seal both containers, which gasket is placed between thebead 12 and the flange 13 on the body of the container 11. As far as thebroad features of my invention are concerned, it is lmniaterial whetherone gasket or two gaskets are utilized, one between the head of theouter container and the flan e'of the inner container, and the othertween the flange of the inner container and the flange of the cover.However, when a single gasket is employed, as illustrated in Figs. 2 and3, it is important that the flange 15 of the cover project outwardlyfurther than the ,flange 13 of the inner container, as will appearpresently.

For the purpose of closing both container bodies, in one closingoperation, a sealing ring 18 lsemployed, this being, a continuous ringhaving separable ends, which can be formed by overlapping the ends andspot welding or otherwise fastening them together, and being providedalso with a downwardly extending flange17 which fits around the head 12,and

having a horizontal inwardly extending portion which overlies the flange15'of the cover 14.

The downwardly extending flange 17 of the sealing ring is preferablycontinuous, and in the closing operation a closing tool is em ployedwhich first presses the parts down onto gasket 16, and then crimpsspaced portions 17 of the flange 17 inwardly under the bead, leavingbetween the crimped portions17 uncrimped portions This type of sealingring and the described method of closing is more fully set forth in apending application filed by me August 19,

1926, Serial No. 130,215, wherein the sealing ring is employed for theclosure of a single container, It may be here stated, however, that inthe closing operation the crimped portions 17 are bent inwardly tightlyagainst the underside of the bead and generally incontact with the bodyof the container beneath its the. bead, these portions being crimped in-"wardlya isubstantially:right angles; and in this crimping operation,the intervening uncrimped port-ions 17 are slightly drawn inwardly andwhere they merge with thecrimped portions they are curved inwardly,

forming the equivalent of curved arches joining the crimped portions andadding considerably to the strength of the top portion of the closedcontainer.

With the preferred embodiment of my invention wherein a single gasket isemployed,

during this closing operation the gasket is not onl highly compressedbetween the bead 12 an the flange 13 but inasmuch as the flange 15extends outwardly beyond the flange 13, the

gasket, by its expansion around or outside of the flange 13, andgenerally also around or outside of the flange 15, efliectively sealsthe inner container as well, as that leakage of powder from the innercontainer aswell as,

leakage of liquid from the outer container is effectively prevented bythe single gasket 16.

The single gasket, with the sealing ring and with the flangesproportioned substantially as herein described and illustrated,effectively seals both containers as above explained. It is obviouslycheaper than a construction employing two gaskets and more economicalfrom the assembling aspect, but, as already stated, I regard it withinthe scope of my invention to utilize two gaskets, in which event thehorizontal flanges on the inner container and cover respectively mayextend outwardly co-extensively. The construction when employing twoseparate gaskets is illustrated in Fig. 4, wherein the flanges on theinner container and cover are designated respectively 13 and 13 and thetwo gaskets, one between the bead and the flange 13 and the otherbetween the latter and the flange 15 are designated respectively 16 and16*. With the two gaskets, the sealing of both. container bodies isaccomplished at the same time and by the use of one sealing ring, as inthe first 1 described construction.

1 as being adapted preferably for receiving respectively the liquid andpowder for making aluminum or bronze paint, it is obvious that they maybe employed for-the shipment of other materials.

I do not desireto be confined to a sealing ring as an element se aratefrom andin'dependent of the cover th ugh that arrangement is preferred,for in some instances, the outer sealing flange may be made an integralpart of the flange 15 of the cover. In that event, to remove the coverthe inwardly crimped portions will be pried outwardly with a suitabletool.

It will be apparent, furthermore, that the location of the gasket 16beneath the flange 13 of the inner container body is not essential,since the placing of the gasket above that flange will still accomplishthe sealing of the two container bodies with a single gasket, so long asthe flange 13 extends outwardly a less distance than the head 12 and theperipheral portion 15 of the cover. In both. cases the inner portion ofthe gasket seals one container body and the outer portion of the gasketseals the other container body. Therefore, I do not desire to beconfined to the precise details shown and described but aim in my claimsto cover all modifications which do not involve a departure from thespirit and scope of my invention.

Having thus described my invention, what I claim is: I
